Abstract
Fumed silicon dioxide powder in the form of aggregated primary particles having a BET surface area of 175±15 m2/g and a thickening effect, based on the BET surface area, of greater than 18 mPas g/m2 is hydrophobicized with polydimethylsiloxane. This hydrophobic fumed silica has a BET surface area of 110±25 m2/g. It can be used in epoxy resins. These epoxy resins in turn can be used as adhesives.
